The work considers the influence of weak external magnetic field on anharmonic Josephson's nanocontacts. The coordinate dependences of phase differences ϕ ( x ), superconducting current I s ( x ) and magnetic field H ( x ) anharmonic nanocontacts were found. It was defined the anharmonism parameter increase leads to phase difference ϕ ( x ) decaying faster, and penetration of magnetic field decreases. It was shown the considered contacts react on external weak magnetic field in more passive way.
